my map (with a handy picture of the buttons).

Put it together as was looking for an easier way of using all 4 traktor decks without constant swapping/toggling of deck controls and also wanted dedicated fx controls for each deck (a and b).

As i only ever really used the bass knob (always have ever since starting on vinyl 10 years ago) i opted to use them as fx controls, and turned the fx section into sampler controls.
